You can see in the pics crazyates posted that we're using an IBM 2000w PSU. Three delta fans on the side keep it nice and cold without having to open the case. 1 PSU feeds 4 AntMiners nicely.
As far as hot wires, we had an AntMiner on the test bench running on a 750w ATX PSU but had a cheesy molex to PCIe adapter that ended up putting all the load onto just 1 pair of about 18awg wire. When we noticed hot cables and the yellow turning brown, we moved to the correct set of cables (PSU is modular). Not only are the cables now running nice and cool, but it's also pulling 30watts less from the wall!!!

if you gave it another minute you wouldve seen a nice little blaze
I used one of those before that was a 8pin ATX -> 6 pin PCI that was rated 18AWG (4 wires for each polarity, or <50W each shouldnt be a problem at all) which burtst into a small fireball within 3 minutes of being installed and switching on the PSU.
don't rely on ebay cables for mining rigs - they are not designed for large loads
